And now here is the daf 2 mutant.

We mate them. They have sort of mutant offspring.

Take care, in this training, to be a good mutant.

But at that time, most of the mutant worms are still alive.

And next you're going to see the long lived mutant when it's young.

Some of the highlights were things like The Terminator, Aladdin, the Teenage Mutant Hero Turtles.

And to participate, for a mutant, there is a minimum of exercise, a minimum of sport.

So, I started out in '95 with this exhibition that was called Mutant Materials in Contemporary Design.

We genetically engineer bacteria.

That's why every morning, now, because you are a good mutant, you will raise your angle of view.

So in a daf 2 mutant you see that I have the X drawn here through the receptor.

How does nature repel bacteria?

What was actually interesting to us was not that the bacteria made light, but when the bacteria made light.

And many of these different genes, we've shown, actually contribute to the long lifespan of the daf 2 mutant.

That's how it works. That's why we don't see the long lifespan, until we have the daf 2 mutant.

Bacteria are incredibly multi drug resistant right now, and that's because all of the antibiotics that we use kill bacteria.

We heard that bacteria eat oil?

Without water, the bacteria won't survive.

Bonnie Bassler on how bacteria talk

To take an example close to home there are over 500 species of bacteria now known friendly bacteria living symbiotically in your mouth and throat probably necessary to your health for holding off pathogenic bacteria.

And we were really optimistic that we could find something because there had been a report of a long lived mutant.

Is your water bottle harbouring dangerous bacteria?

And it's killing bacteria. It's eating them.

Bacteria always control pathogenicity with quorum sensing.

The smallest bacteria is about 200 nanometers.

So we went back to molecular biology and started studying different bacteria, and what we've found now is that in fact, bacteria are multilingual.

Mud and minerals become substrate there are bacteria.

These vibrios, these bacteria, can actually infect people.

So, the bacteria grows hair on the crab.

Already what were thought to be bacteria for generations have been found to compose, instead, two great domains of microorganisms true bacteria and one celled organisms the archaea, which are closer than other bacteria to the eukaryota, the group that we belong to.

We was so, so stupid. The most stupid bacteria.

Bacteria are the oldest living organisms on the earth.

So replacing the bacteria DNA with virus DNA turns the bacteria into a factory for making viruses that is, until it's so filled with viruses that it bursts.

You look in his intestines. There are billions of bacteria.

The main characters in the story are bacteria and viruses.

But that's not the only way that viruses infect bacteria.

Those fungi and bacteria are as highly evolved as humans.

But that number of bacteria species can be found in one gram of soil, just a little handful of soil, in the 10 billion bacteria that would be there.

And so, the question for my lab is whether you want to think about all the good things that bacteria do, or all the bad things that bacteria do.

The real bacteria and viruses are so small we can't see them without a microscope, and you guys might know bacteria and viruses because they both make us sick.

And these are mineral deposits that are also made by bacteria.

We think bacteria made the rules for how multicellular organization works.

And when the molecule hits a certain amount that tells the bacteria how many neighbors there are, they recognize that molecule and all of the bacteria turn on light in synchrony.

But what we were really thinking about is that most of the time bacteria don't live by themselves, they live in incredible mixtures, with hundreds or thousands of other species of bacteria.
